OS changes can break main, with no way to fix with the tool #3
Description
After a software upgrade, libopenblas.so changed locations such that /lib/security/go-face-unlock/main was unable to be (runtime) linked. The fix was to simply re-compile and re-install main, but main install refuses to re-install itself if it detects the destination directory.
A work-around is to read the code, determine what install() is doing, and manually repeat. The main issue for a user is making sure they get the file owner and permissions right.
A better fix would be if main install would re-install (and re-permission) the binary executable whether or not the destination directory exists.
